Abstract

The valve piece of a toilet-tank discharge valve is moved into its open position by the release activation of an associated activating mechanism. It usually remains in this position until the flushing process is complete and the drops back into the closed position. The valve piece can also be moved back into its closed position ahead of time by discontinuance activation. The activating mechanism has a shift mechanism that can be reversed in its operating direction by a change of state in the toilet tank associated with release activation in such a way that discontinuance activation can result from renewed activation of one and the same activating mechanism in the same direction as during release activation. The device is convenient to operate and provides a wide range of possible ways of designing the operating element from the aspect of appearance. Simple remote operating devices can also be employed. The shift mechanism can also be shifted back in accordance with the further change of state in the tank resulting from discontinuance activation and from regular closure.

Description

Die Erfindung betrifft ein Spülkasten-Ablaufventil mit einem Ventilstück, das durch die Auslösebetätigung einer zugeordneten Betätigungseinrichtung in die Offenstellung überführbar ist, sich 'in dieser bis zum Abschluß des Spülvorganges hält und dann in die Schließstellung fällt, wobei durch eine Unterbrechungsbetätigung der Betätigungseinrichtung das Ventilstück vorzeitig in die Schließstellung zurückbewegbar ist.The invention relates to a cistern drain valve with a valve piece, which can be moved into the open position by the actuation of an associated actuating device, stays in this until the washing process is completed and then falls into the closed position, the valve piece prematurely due to an actuation of the actuating device being interrupted can be moved back into the closed position.

Bei den bislang bekannten Ablaufventilen dieser Art kann der Spülvorgang vorzeitig dadurch unterbrochen werden, daß das Bedienungselement in zur Auslösebewegung umgekehrter Richtung betätigt wird. Der Aufbau ist zwar einfach, wenn aber das Bedienungselement nicht als Wipptaste ausgebildet ist, muß es in umgekehrter Richtung betätigt werden, und dieses ist wenig bedienungsfreundlich. Außerdem muß das Bedienungselement überhaupt über eine entsprechende Angriffsmöglichkeit verfügen. Dies ist aber für Spülkästen, bei denen die Betätigungstaste aus Design-Gründen z. B. oberflächenbündig in der Mitte des Deckels angeordnet ist, praktisch nicht gegeben.In the previously known drain valves of this type, the flushing process can be interrupted prematurely by actuating the operating element in the opposite direction to the triggering movement. The structure is simple, but if the control element is not designed as a rocker switch, it must be operated in the opposite direction, and this is not very easy to use. In addition, the control element must have an appropriate attack option at all. But this is for cisterns in which the actuation button for design reasons such. B. is arranged flush with the center of the lid, practically not given.

Ein wesentlicher Nachteil der herkömmlich gegenläufigen Unterbrechungsbetätigung besteht auch darin, daß die üblichen Fernbetätigungen, die normalerweise nur über eine Wirkrichtung verfügen, nicht anzuwenden sind.A major disadvantage of the conventionally opposite interruption actuation is that the usual remote actuations, which normally only have one direction of action, cannot be used.

Aus der US-A-2 927 327 sowie DE-U-7 520 800 und DE-U-8 113 520 sind ferner Spülkasten-Ablaufventile bekannt, bei denen eine vorzeitige Unterbrechung des Spülvorganges durch einen zweiten, gesonderten Betätigungselementenzug verwirklicht wird. Man hat somit einen Betätigungselementenzug zum Auslösen des Spülganges sowie einen weiteren Betätigungselementenzug zum im Bedarfsfall vorzeitigen Beenden des Spülvorganges zur Verfügung. Diese Ausgestaltung ist ebenfalls wenig bedienungsfreundlich, bietet zu Verwechslungen Anlaß, läßt sich nicht sinnvoll mit den üblichen Fernbetätigungen kombinieren und hat darüberhinaus den Nachteil des baulichen Aufwandes des zweiten Betätigungselementenzuges im Spülkasten, wodurch sich auch die Störanfälligkeit der Armatur erhöht.Cistern drain valves are also known from US-A-2 927 327 and DE-U-7 520 800 and DE-U-8 113 520, in which a premature interruption of the flushing process is realized by a second, separate actuating element train. There is thus an actuating element train for triggering the rinsing cycle and a further actuating element train for prematurely ending the rinsing process if necessary. This configuration is also not very easy to use, offers confusion, cannot be reasonably combined with the usual remote controls and also has the disadvantage of the structural complexity of the second actuating element train in the cistern, which also increases the susceptibility to failure of the valve.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Spülkasten-Ablaufventil der gattungsgemäßen Art zu schaffen, mit dem bei einfachem Aufbau der Spülvorgang durch eine zweite Betätigung des Bedienungselementes in derselben Richtung wie bei der Auslösebetätigung zu unterbrechen ist.The present invention is therefore based on the object of providing a cistern drain valve of the generic type, with which the flushing process can be interrupted by a second actuation of the operating element in the same direction as when the trigger is actuated, with a simple structure.

Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1.The solution according to the invention results from the characterizing part of patent claim 1.

Die Wirkungsrichtung des Übertragungsmechanismus zwischen Bedienungselement und Ventilstück wird damit durch den jeweils bei einer Betätigung angetroffenen Zustand des Spülkastens automatisch vorgegeben. Ist der Spülkasten gefüllt, wird mit der Betätigung das Ablaufventil geöffnet (Auslösebetätigung). Eine zweite gleichgerichtete Betätigung während des Spülvorganges schließt dagegen das Ablaufventil vorzeitig (Unterbrechungsbetätigung).The direction of action of the transmission mechanism between the operating element and the valve piece is thus automatically predetermined by the state of the cistern that is encountered when actuated. If the cistern is filled, the drain valve is opened when it is actuated (trigger actuation). A second rectified actuation during the flushing process, on the other hand, closes the drain valve prematurely (interruption actuation).

Unterbleibt die Unterbrechungsbetätigung, schließt das Ablaufventil nach Abgabe der vollen Spülmenge selbsttätig. Der Füllvorgang setzt entsprechend später ein. In beiden Fällen aber löst eine weitere Betätigung, ggf. erst bei entsprechend hohem Wasserstand, erneut den Spülvorgang aus.If the interruption is not activated, the drain valve closes automatically after the full flush volume has been dispensed. The filling process starts later accordingly. In both cases, however, a further actuation, possibly only when the water level is high, triggers the rinsing process again.

Ein derartiges Spülkasten-Ablaufventil ist sehr bedienungsfreundlich. Es läßt bezüglich des Designs des Bedienungselementes, beispielsweise der Drucktaste, alle Möglichkeiten offen, insbesondere auch eine oberflächenbündige und mittige Anordnung im Spülkastendeckel. Es können auch einfach aufgebaute Fernbetätigungen eingesetzt werden.Such a cistern drain valve is very easy to use. It leaves all possibilities open with regard to the design of the control element, for example the push button, in particular also a surface-flush and central arrangement in the cistern lid. Simple remote controls can also be used.

Weitere bevorzugte Ausgestaltungen eines derartigen Spülkasten-Ablaufventiles sind in den Unteransprüchen gekennzeichnet. Es sind dort Beispiele baulich einfacher Umsteuervorrichtungen aufgezeigt, die auf verschiedene, sich durch die Ventilöffnung und -schließung ergebende Zustandsänderungen im Spülkasten, ansprechen. Als Steuergrößen können zum Beispiel die Strömungsgeschwindigkeit des Spülwassers, die Höhe des Wasserspiegels, das Verhalten des Spülkasten-Füll-Ventils oder aber die jeweilige Stellung des Ablaufventils selbst dienen.Further preferred embodiments of such a cistern drain valve are characterized in the subclaims. There are shown examples of structurally simple reversing devices which respond to various changes in the state of the cistern resulting from the valve opening and closing. For example, the flow rate of the flushing water, the height of the water level, the behavior of the cistern fill valve or the respective position of the drain valve itself can serve as control variables.

Schematisch dargestellte Ausführungsbeispiele von erfindungsgemäßen Spülkasten-Ablaufventilen werden nachstehend näher beschrieben.Exemplary embodiments of cistern drain valves according to the invention are shown schematically below.

Figur 1 zeigt den gefüllten und spülbereiten Spülkasten 1. Die obere Drucktaste 2 ist über die-Stange 3 mit dem Schaltgehäuse 4 verbunden. Dies bewegt sich mit der Auslösebetätigung (oberer ausgefüllter Pfeil) relativ zum senkrechten Schaltarm 5 des Winkelhebels 6 und schwenkt ihn nach links. Der gabelartige Arm des Winkelhebels 6 öffnet dabei das angekoppelte Ventilstück 7 und der Spülvorgang setzt ein. Nicht dargestellte Vorrichtungen (Schwimmerkörper, Sperrklinken o. ä.) sorgen in üblicher Weise dafür, daß auch nach Rückhub der Drucktaste 2-also nach Abschluß der Auslösebetätigung - das Ventilstück 7 geöffnet bleibt.Figure 1 shows the filled and rinse-ready cistern 1. The upper push button 2 is connected to the switch housing 4 via the rod 3. This moves with the actuation (upper filled arrow) relative to the vertical switching arm 5 of the angle lever 6 and pivots it to the left. The fork-like arm of the angle lever 6 opens the coupled valve piece 7 and the flushing process begins. Not shown te devices (float, pawls, etc.) ensure in the usual way that the valve piece 7 remains open even after the pushbutton 2 has been lifted back — that is, after the triggering operation has been completed.

Wird während des Spülvorganges erneut betätigt (Unterbrechungsbetätigung - oberer nicht ausgefüllter Pfeil), wiederholt sich die Relativbewegung des Schaltgehäuses 4 zum jetzt links stehenden Schaltarm 5. Jetzt aber wird er nach rechts geschwenkt, und das angekoppelte Ventilstück 7 schließt (unterer nicht ausgefüllter Pfeil).If you press again during the flushing process (interruption actuation - upper arrow not filled in), the relative movement of the switching housing 4 to the switching arm 5 now on the left is repeated, but now it is swiveled to the right and the connected valve piece 7 closes (lower arrow not filled in).

Verantwortlich für die unterschiedlichen Wirkungsrichtungen des Schaltgehäuses 4 sind die Steuerglieder 8, 9 oder 10. Je nach Betriebszustand des Spülkastens nehmen sie unterschiedliche Stellungen ein und übertragen diese über die Koppelstange 11 auf ein im Schaltgehäuse 4 angeordnetes Schaltstück 41.The control elements 8, 9 or 10 are responsible for the different directions of action of the switch housing 4. Depending on the operating state of the cistern, they assume different positions and transmit them via the coupling rod 11 to a switching element 41 arranged in the switch housing 4.

Das Steuerglied 8 reagiert auf den Spülstrom. Es ist als drehbar gelagerter Winkelhebel ausgebildet. Der Auftrieb der am waagerechten Arm angeordneten Schwimmerkammer 81 sorgt für die gezeichnete Ausgangsstellung. Dabei definiert der senkrechte Arm, der in die Koppelstange 11 eingreift, deren linke Stellung. Nach der Auslösebetätigung setzt die Strömung ein. Sie überwindet die Auftriebskraft der Schwimmerkammer 81 und schwenkt den Winkelhebel in Pfeilrichtung. Dabei wird die Koppelstange 11 in ihre rechte Stellung bewegt.The control element 8 reacts to the flushing current. It is designed as a rotatable angle lever. The buoyancy of the float chamber 81 arranged on the horizontal arm ensures the drawn starting position. The vertical arm, which engages in the coupling rod 11, defines its left position. After the actuation of the trigger, the flow begins. It overcomes the buoyancy of the float chamber 81 and swivels the angle lever in the direction of the arrow. The coupling rod 11 is moved into its right position.

Das Steuerglied 9 reagiert auf den Wasserstand im Kasten. Auch dieses Element ist als drehbar gelagerter Winkelhebel ausgebildet, dessen senkrechter Arm auf die Koppelstange 11 wirkt. Am waagerechten Arm ist die Schwimmerkammer 91 angeordnet, deren Auftrieb für die dargestellte Ausgangsstellung sorgt. Nach der Auslösebetätigung sinkt der Wasserspiegel. Die Auftriebskraft fällt weg und das Gewicht der Wasserkammer 92 schwenkt das Steuerglied 9 in Pfeilrichtung, der die Koppelstange 11 folgt.The control member 9 reacts to the water level in the box. This element is also designed as a rotatably mounted angle lever, the vertical arm of which acts on the coupling rod 11. The float chamber 91 is arranged on the horizontal arm, the buoyancy of which ensures the starting position shown. After the trigger is activated, the water level drops. The buoyancy is eliminated and the weight of the water chamber 92 pivots the control member 9 in the direction of the arrow, which the coupling rod 11 follows.

Das Steuerglied 10 reagiert auf den Ausfluß des Füllventiles 13. Im Ruhezustand sorgt die Druckfeder 101 für die linke Stellung des Kolbens 102 und damit der Koppelstange 11. Nach der Auslösebetätigung sinkt Wasserspiegel, und das Füllventil 13 öffnet. Die Drossel 132 der Fülleitung 131 sorgt für Druckaufbau in der Steuerleitung 103. Der Kolben 102 schiebt das Steuerglied 10 und mit ihm die Koppelstange 11 nach rechts.The control member 10 reacts to the outflow of the filling valve 13. In the idle state, the compression spring 101 ensures the left position of the piston 102 and thus the coupling rod 11. After the actuation, the water level drops and the filling valve 13 opens. The throttle 132 of the filling line 131 builds up pressure in the control line 103. The piston 102 pushes the control element 10 and with it the coupling rod 11 to the right.

Figur 2 zeigt in vergrößertem Maßstab das Schaltgehäuse 4'. In ihm ist das mit der Koppelstange 11 verbundene Schaltstück 41' waagerecht verschiebbar geführt. Die Ausgangsstellung des Schaltstückes 41' und des mit ihm zusammenwirkenden gabelartigen Schaltarms 5' ist in ausgezogenen Linien dargestellt. Mit der Auslösebetätigung (oberer Pfeil) wird die gestrichelt dargestellte Schaltstellung erreicht, und der Spülvorgang setzt ein.Figure 2 shows the switch housing 4 'on an enlarged scale. In it the switching piece 41 'connected to the coupling rod 11 is guided to be horizontally displaceable. The starting position of the switching element 41 'and of the fork-like switching arm 5' interacting with it is shown in solid lines. When the trigger is actuated (upper arrow), the switch position shown in dashed lines is reached and the flushing process begins.

Damit treten im Kasten die erwähnten Zustandsänderungen ein und eines der Steuerglieder 8, 9 oder 10 schiebt das Schaltstück 41' in seine rechte, punktiert gezeichnete Stellung. In diesem Zustand schwenkt eine erneute Betätigung den Schaltarm 5' von seiner gestrichelt gezeichneten Stellung in die Ausgangsstellung zurück, das heißt, der Spülvorgang wird unterbrochen. Unterbleibt diese Unterbrechungsbetätigung, schließt das Ventilstück 7 selbstätig. Der Kasten füllt erneut, und alle Elemente nehmen wieder ihre Ausgangsstellung ein.Thus, the changes in state mentioned occur in the box and one of the control elements 8, 9 or 10 pushes the switching element 41 'into its right, dotted position. In this state, a new actuation pivots the switching arm 5 'back from its position shown in dashed lines to the starting position, that is, the rinsing process is interrupted. If this interruption actuation is omitted, the valve piece 7 closes automatically. The box fills again and all elements return to their starting position.

Eine weitere sehr zweckmäßige Steuergröße für die Wirkungsrichtung des Schaltgehäuses 4 ist die Stellung des Ventilstückes 7. Diese mechanische Zustandsänderung kann direkt vom Schaltarm 5 auf das Schaltgehäuse 4 zurückgekoppelt werden, was in Figur 1 symbolisch durch die Pfeillinie dargestellt ist. Eine mögliche Ausführungsform ist in den Figuren 3 und 4 wiedergegeben.Another very useful control variable for the direction of action of the switch housing 4 is the position of the valve piece 7. This mechanical change in state can be fed back directly from the switch arm 5 to the switch housing 4, which is symbolically represented in FIG. 1 by the arrow line. A possible embodiment is shown in Figures 3 and 4.

Um die Darstellung zu verdeutlichen, sind abweichend von Figur 1 die stark ausgezogenen Steuerkonturen des symmetrischen Schaltgehäuses 4" ortsfest dargestellt. Die mit jeder Betätigung sich einstellende Relativbewegung wird daher auf der Zeichnung vom Lagerzapfen 51 des ebenfalls symmetrischen Schaltarmes 5" ausgeführt. Die ausgezogenen Linien in Figur 3 zeigen seine Ausgangsstellung. An den Enden sind jeweils über elastische Verbindungszonen 52 die Hebelarme 53 befestigt, die jeweils am unteren Ende den linken Steuerzapfen 54 und den rechten Steuerzapfen 55 tragen. Diese arbeiten mit den ortsfesten Steuerkanten 42 und deren Anlaufschrägen 43 zusammen. Der Mittelarm 56 trägt am unteren Ende den Steuerzapfen 57, der mit den ortsfesten Steuerkanten 44 und deren Anlaufschrägen 45 zusammenwirkt. Die die Steuerzapfen tragenden Arme sind jeweils senkrecht zur Zeichenebene elastisch, so daß die Anlaufschrägen keine Behinderung darstellen.In order to clarify the illustration, in contrast to FIG. 1, the strongly drawn out control contours of the symmetrical switch housing 4 "are shown in a fixed position. The relative movement which occurs with each actuation is therefore carried out on the drawing by the journal 51 of the likewise symmetrical switch arm 5". The solid lines in Figure 3 show its starting position. At the ends, the lever arms 53 are each attached via elastic connecting zones 52, each of which carries the left control pin 54 and the right control pin 55 at the lower end. These work together with the fixed control edges 42 and their bevels 43. The center arm 56 carries at the lower end the control pin 57, which cooperates with the fixed control edges 44 and their run-on slopes 45. The arms carrying the control pins are each elastic perpendicular to the plane of the drawing, so that the bevels do not represent an obstacle.

Bewegt sich bei einer Betätigung der Lagerzapfen 51 in Pfeilrichtung nach oben (entspricht der Relativbewegung zwischen Schaltgehäuse 4 und Schaltarm 5 in Figur 1), schwenkt der Schaltarm 5" um seine linke elastische Verbindungszone, da hier die Aufwärtsbewegung durch den hinter die Steuerkante 42 greifenden Steuerzapfen 54 behindert wird. Auf dem Weg zu der gestrichelt dargestellten Endlage gleitet der Steuerzapfen 57 des Mittelarmes 56 über die Anlaufschräge 45 der Steuerkante 44 und rastet hinter dieser ein.Moves upward in the direction of the arrow when the bearing pin 51 is actuated (corresponds to the relative movement between the switch housing 4 and the switch arm 5 in FIG. 1), the switch arm 5 "pivots about its left elastic connecting zone, since here the upward movement through the control pin reaching behind the control edge 42 54. On the way to the end position shown in dashed lines, the control pin 57 of the center arm 56 slides over the run-on slope 45 of the control edge 44 and engages behind it.

Diese Endlage ist die in Figur 4 in ausgezogener Linie dargestellte Ausgangslage für den folgenden Rückhub der Betätigung (rückläufige Relativbewegung des Lagerzapfens 51 - s. Pfeil). Dabei gleitet der Steuerzapfen 57 hinter seiner Steuerkante 44 nach unten und verriegelt die Endstellung des Schaltarmes 5". Der linke Steuerzapfen 54 löst sich von seiner Steuerkante 42. und federt in seine ursprüngliche Relativstellung zum Steuerarm 5" zurück. In der. Endphase des Rückhubes gleitet der rechte Steuerzapfen 55 auf die Anlaufschräge 43, deren hochstehende linke Begrenzungskante die Verriegelung der Schwenkstellung übernimmt, bevor der Steuerzapfen 57 seine Steuerkante 44 verläßt. Die End-This end position is the starting position shown in solid line in FIG. 4 for the subsequent return stroke of the actuation (retrospective relative movement of the bearing journal 51 - see arrow). The control pin 57 slides downward behind its control edge 44 and locks the end position of the switching arm 5 ". The left control pin 54 detaches from its control edge 42. And springs back into its original relative position to the control arm 5". In the. Final phase of the return stroke, the right control pin 55 slides onto the bevel 43, the upstanding left boundary edge of which locks the pivot position before the control pin 57 leaves its control edge 44. The final

stellung des RĂĽckhubes ist gestrichelt dargestellt. Der rechte Steuerzapfen 55 ist hinter die Steuerkante 42 eingerastet.position of the return stroke is shown in dashed lines. The right control pin 55 is locked behind the control edge 42.

Bei der geänderten Ausgangsstellung bewirkt ein erneuter Doppelhub - also eine Unterbrechungsbetätigung - wegen des symmetrischen Aufbaues der beschriebenen Schalteinrichtung den entgegengesetzten Bewegungsablauf. Damit wird der Schaltarm 5" in die ursprüngliche Position zurückgeschwenkt.In the changed initial position, a new double stroke - that is, an interruption actuation - causes the opposite movement because of the symmetrical structure of the switching device described. The switching arm 5 "is thus pivoted back into the original position.

Die Steuerzapfen werden in unbetätigtem Zustand nicht durch die ortsfesten Steuerkonturen behindert. Der Schaltarm 5" kann daher auch ohne erneuten Doppelhub durch von außen angreifende geringfügige Kräfte, die lediglich die Reibung des Lagerzapfens 51 überwinden müssen, in seine ursprüngliche Ausgangsstellung zurückgeschwenkt werden. Dies ist durch die nicht ausgefüllten Pfeile in Figur 4 dargestellt. Insofern wird die Schließbewegung des am Schaltarm 5" angekoppelten Ventilstückes 7 nicht behindert, wenn der gesamte Kasteninhalt abgelaufen ist.The control pins are not hindered by the fixed control contours when not actuated. The switching arm 5 "can therefore also be pivoted back into its original starting position by means of minor forces acting from outside, which merely have to overcome the friction of the bearing journal 51, without a renewed double stroke. This is shown by the arrows which have not been filled in in FIG. 4. In this respect, the closing movement of the valve piece 7 coupled to the switching arm 5 "is not hindered when the entire contents of the box have expired.

Die bisher geschilderten Funktionsprinzipien sind nicht auf eine mechanische Betätigungseinrichtung beschränkt. Als Beispiel für die generelle Anwendbarkeit ist in Figur 5 ein hydraulisch betätigtes Ablaufventil dargestellt. Mit der Auslösebetätigung (oberer ausgefüllter Pfeil) wird das Betätigungsventil 14 geöffnet. Der vor dem Füllventil 13 anstehende Leitungsdruck gelangt über die Steuerleitung 15 und das Schaitventi) 16 unter den Kolben 71, und das angekoppelte Ventilstück 7 öffnet. Alternativ kann jedes der in Figur 1 dargestellten Steuerglieder über die Koppelstange 11 das Schaltventil 16 nach rechts verschieben. Eine Unterbrechungsbetätigung während des Spülvorganges (oberer nicht ausgefüllter Pfeil) wird dann den Kolben 71 von oben mit Druck beaufschlagen, und das Ventilstück 7 schließt (unterer nicht ausgefüllter Pfeil).The functional principles described so far are not limited to a mechanical actuation device. A hydraulically operated drain valve is shown in FIG. 5 as an example of the general applicability. The actuation valve 14 is opened when the trigger is actuated (upper filled arrow). The line pressure in front of the filling valve 13 reaches the piston 71 via the control line 15 and the switching valve 16, and the coupled valve piece 7 opens. Alternatively, each of the control elements shown in FIG. 1 can shift the switching valve 16 to the right via the coupling rod 11. An interruption actuation during the rinsing process (upper unfilled arrow) will then apply pressure to the piston 71 from above, and the valve piece 7 closes (lower unfilled arrow).

Die Pfeillinie deutet die weitere Möglichkeit an, die Wirkungsrichtung des Schaltventiles 16 direkt durch die Stellung des Ventilstückes 7 vorzugeben. Ein Ausführungsbeispiel ist in Figur 6 wiedergegeben.The arrow line indicates the further possibility of specifying the direction of action of the switching valve 16 directly through the position of the valve piece 7. An embodiment is shown in Figure 6.

Die vom nicht dargestellten Betätigungsventil 14 abgehende Steuerleitung 15 führt sowohl zum Schaltventil 16' als auch zum Vorsteuerventil 17. Dies ist mit dem Ventilstück 7 gekoppelt.The control line 15 leading from the actuating valve 14, not shown, leads both to the switching valve 16 'and to the pilot valve 17. This is coupled to the valve piece 7.

Mit der Auslösebetätigung läuft der Druckimpuls über das Vorsteuerventil 17 auf die rechte Stirnseite des Schaltventiles 16' und schiebt dies nach links. Diese Stellung ist selbsthaltend, also unabhängig von der weiteren Bewegung des Vorsteuerventiles 17.When the trigger is actuated, the pressure pulse runs via the pilot valve 17 to the right end of the switching valve 16 'and pushes it to the left. This position is self-holding, that is to say independent of the further movement of the pilot valve 17.

Der auf die Unterseite des Kolbens 72 wirkende Druck wird daher in der Ă–ffnungsphase des Ablaufventiles nicht unterbrochen.The pressure acting on the underside of the piston 72 is therefore not interrupted in the opening phase of the drain valve.

Nach der Auslösebetätigung wird das Schaltventil 16 durch Federkraft wieder in seine neutrale Mittelstellung zurückbewegt.After the actuation of the trigger, the switching valve 16 is moved back into its neutral central position by spring force.

Mit der Unterbrechungsbetätigung schaltet der Druckimpuls wegen der geänderten Stellung des Vorsteuerventiles 17 das Schaltventil 16' selbsthaltend nach rechts, und der Kolben 72 bewegt das Ventilstück 7 in Schließrichtung. Damit wird wieder der Ausgangszustand erreicht. Dies ist auch ohne Unterbrechungsbetätigung der Fall, wenn nach Ablauf der Spülmenge das Ventilstück 7 selbsttätig schließt. Hierzu ist das Vorsteuerventil 17 soweit reibungsfrei zu halten, daß diese Bewegung nicht behindert wird.With the interruption actuation, the pressure pulse switches the switching valve 16 ′ to the right in a self-retaining manner due to the changed position of the pilot valve 17, and the piston 72 moves the valve piece 7 in the closing direction. The initial state is thus reached again. This is also the case without interruption actuation if the valve piece 7 closes automatically after the flushing quantity has expired. For this purpose, the pilot valve 17 is to be kept friction-free to the extent that this movement is not hindered.

Es liegt auf der Hand, daß die dargestellten Ausführungsbeispiele nur einen Bruchteil der Möglichkeiten wiedergeben, den Grundgedanken der Erfindung zu realisieren.It is obvious that the exemplary embodiments shown represent only a fraction of the possibilities for realizing the basic idea of the invention.
